A Modification is an alteration to a game. Yandere simulator modifications can be created some programs by anyone in every game's release, and are not supported or endorsed by yanderedev.

All modifications are to be entirely free, and may be downloaded and used by anybody. However, there are restrictions on editing and distributing the modification, so always ask permission from the author.

Modifications are mainly only used on PC versions of Unity3D Games. There are methods of modifying other OS versions, like Android. but these are complex and can't yet be done.

Beware! Yandere Simulator is actually already complied as a "game", with that means, you "can't do anything" without some sort of "Source" and "Copyright", and the only one who have it is DEV's. (AKA.: yanderedev)
